STERILIZER Filed Sept. 1, 1938 2 Sheets-Sheet 2 Inventor 1 flarry L.Wzzfia By gammy/5M Z2 mwl W amma- Patented Feb. 27, 1940 UNITED STATESPATENT OFFICE 1 Claim.

My invention relates to improvements in sterilizers for use moreparticularly in the kitchen in sterilizing dishes, pots and pans and thelike, and other cooking and table accessories.

5 The principal object of the invention is to provide an inexpensive,eiiicient device of this char-- acter for use in sterilizing with hotwater from the usual kitchen hot water supply line and which is readilyportable and can be used in any sink.

10 Other, and subordinate objects, are also comprehended by myinvention, all of which, together with the precise nature of myimprovements, will be readily understood when thesucceeding descriptionand claim are read with reference to 18 the drawings accompanying andforming part of this specification.

In said drawings:

Figure 1 is a view partly in front elevation and partly in longitudinalsection of sterilizing ab- 20 paratus constructed in accordance with myinvention.

Figure 2 is a view partly in horizontal section and partly in top plan.

Figure 3 is a. view in transverse section taken 25 on line 33 of Figure1 looking in the direction indicated by the arrows.

Figure 4 is a view in end elevation drawn to a reduced scale, and

Figure 5 is a detail view in transverse section 30 taken .on line 55 ofFigure 2.

Referring to the drawings by numerals, the sterilizing apparatus of myinvention comprises a vault l including a rectangular pan 2 having abottom 3, front and rear walls 4 and 5 and end 35 walls 6, and acanopy-like top 1 arching upwardly and forwardly over the pan 2 andforming together with extensions 8 of the end walls 6 a hood extendingpart-way over the pan 2 and open at the front side of the apparatus. Acover 9 40 corresponding in shape to that of the described hood ishinged, as at In, to the extensions 8 for opening and closing the openside of said hood and is provided, as at ,I I, with a suitable knob formanipulation of the same. The pan 2 is provided ,5 with an upperright-angled edge flange l2 which seats the lower edge of the cover 9 inthe closed position of said cover. Extending around the pan 2 in theupper part thereof is an internal flange I3 functioning as a seat for arectangular grid 50 M fitting into the pan 2 and removable therefrom.

Extending through one end of the pan 2 horizontally to the approximatecenter thereof is a water inlet pipe l5 spaced close to the back wall 555 and having an upstanding inner end l6 curving upwardly and forwardlyalongside the top I to the open front of the described hood at whichpoint it is provided with a downturned elbow 11 to which there isattached a short length depending pipe section l8. n the lower end ofthe pipe section I8 is a spray nozzle comprising a fitting 20 suitablysecured to said end of the section l8 and a. pair of oppositely curvedperforated spray arms 2| extending from diametrically opposite sides ofthe fitting 20 and perforated along their bottom faces, as at 22, forthe discharge of water therefrom, said arms 2| together with the fitting20 forming a rotating reactive sprinkler disposed well above the gridl4.

Extending forwardly from the inner end l6 of pipe [5 is a pipe section23 having an upturned free end 24 in vertical alignment with the pipesection l8 and in which is suitably mounted a second rotary reactivesprinkler 25 which is a counterpart of that previously described withthe exception that the perforations 26 thereof are in the top of thearms 21 and said arms are oppositely curved relative to arms 25, thesprinkler rotating oppositely relative to that previously describedbeneath the grid it. The pipe I5 is 25 provided externally of the pan 2with any suitable means (not shown) for connection to the hot waterfaucet of the kitchen.

. The manner in which the described apparatus is used and operated willbe manifest. Suflice it 30 to explain, that the articles to besterilized are placed on top of the grid I4 and the hot water introducedinto the vault I by way of the pipe l5 and under pressure, whereby thedescribed sprinklers are rotated in opposite directions from theinventive concept and right is herein reserved to such modifications asfall within the scope of the subjoined claim.

What I claim is: sterilizing apparatus comprising a rectangular vaulthaving a transversely curved top including a front closure, ahorizontally disposed grid in said vault substantially midway betweenthe top 5 and bottom thereof, a water supply pipe extending through oneend of the vault into the latter below said grid and close to the rearwall of the vault, said pipe having an upstanding end in the transversecenter of the vault curving in conformity with the top of the vault andspaced close thereto, said end terminating at the top of the vault inthe longitudinal center thereof, an upper sprinkler mounted on theterminal of said 10 end below the same for rotation about a verticalaxis under reaction incident to the discharge 0! water therefrom, abranch pipe extending 10rwardly and horizontally from said upstandingend in the plane thereof and below said grid, and a lower sprinklermounted on said branch pipe for rotation in the axis of the uppersprinkler under reaction incident to discharge of water therefrom andoppositely relative to the direction of rotation of the sprinkler firstmentioned.
